4.62.020 - Findings and purpose.

The Board of Supervisors finds and determines as follows:

A.

The preservation of vegetation communities and natural areas within the County of Riverside (County) which support species covered by the Multiple Species Habitat Conservation Plan (MSHCP) is necessary to protect and promote the health, safety, and welfare of all the citizens of the county by reducing the adverse direct, indirect, and cumulative effects of urbanization and development and providing for permanent conservation of habitat for species covered by the MSHCP.

B.

The MSHCP was approved by the County of Riverside Board of Supervisors on June 17, 2003; federal and State permits were issues for the MSHCP on June 22, 2004. Riverside County is a Member Agency of the Western Riverside County Regional Conservation Authority (RCA), a joint powers authority comprised of the County and eighteen (18) cities located within western Riverside County.

C.

It is necessary to update as needed certain development impact fees to ensure that all new development within the county pays its fair share of the costs of acquiring and preserving vegetation communities and natural areas within the county and the region which are known to support plant and wildlife species covered by the MSHCP.

D.

A proper funding source to pay the costs associated with mitigating the direct, indirect, and cumulative impacts of development to the natural ecosystems within the county and the region, as identified in the MSHCP, is a development impact fee for residential, commercial, and industrial development (local development mitigation fee). The amount of the fee is determined by the nature and extent of the impacts from the development to the identified natural ecosystems and the relative cost of mitigating such impacts.

E.

The Western Riverside County Regional Conservation Authority (RCA) has prepared an updated fee nexus study entitled "Western Riverside County Multiple Species Habitat Conservation Plan Nexus Fee Study Update" (2020 Nexus Study), and on December 7, 2020, the RCA Board of Directors reviewed the 2020 Nexus Study and directed all RCA Permittees to adopt the updated MSHCP fees.

F.

The MSHCP and the 2020 Nexus Study, a copy of which is on file in the county clerk's office, provides the basis for the imposition of the updated local development mitigation fee on new construction and development projects.

G.

The use of the local development mitigation fee to mitigate the impacts to the county's and the region's natural ecosystems is reasonably related to the type and extent of impacts caused by development within the county.

H.

The costs of funding the proper mitigation of natural ecosystems and biological resources impacted by development within the county and the region are apportioned relative to the type and extent of impacts caused by the development.

I.

The cost estimates for mitigating the impact of development on the county's and the region's natural ecosystem and biological resources, as set forth in the MSHCP, are reasonable and will not exceed the reasonably estimated total of these costs.

J.

The local development mitigation fee collected pursuant to this chapter shall be used to finance the acquisition and perpetual conservation of the natural ecosystems and certain improvements necessary to implement the goals and objectives of the MSHCP.

K.

The detailed administrative procedures concerning the implementation of this chapter shall be contained in the MSHCP Mitigation Fee Implementation Manual adopted December 7, 2020.

L.

The boundary of the Western Riverside County Multiple Species Habitat Conservation Plan Fee Area is the same as the MSHCP boundary as set forth in that document entitled MSHCP Plan Area map dated June 2003, which is on file with the clerk of the board.
